devel/glib12 x11-toolkits/gtk12:
- Convert to USES=libtool and bump dependent ports
- Add INSTALL_TARGET=install-strip
- Remove patches that renamed include directories and libraries so they
didn't conflict with early development versions of glib/gtk 2.0

Remove more tags from pkg-descr files fo the form:
- Name
em@i.l
or variations thereof. While I'm here also fix some whitespace and other
formatting errors, including moving WWW: to the last line in the file.

Bump portrevision due to upgrade of devel/gettext.
The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).
